EASEL.js

PolyhedronGeometry

Base geometry for subdivided polyhedra projected onto a sphere. Each source triangle is split into (detail + 1)² triangles, matching EASEL.js.PolyhedronGeometry, then its vertices are normalized to the requested radius. detail = 0 keeps flat face normals; higher detail uses smooth normals. UVs follow EASEL.js’s spherical mapping and seam correction.
